Abstract
The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting higher data rates. A method performed by a terminal performing a slice-based cell reselection in a wireless communication system is provided. The method includes obtaining information on a network slice access stratum group (NSAG) from a non-access stratum (NAS), in case that a cell in a frequency fulfils cell reselection criteria and does not support the NSAG, identifying whether the cell supports at least one NSAG other than the NSAG, and rederiving a reselection priority for the frequency based on a result of the identification.
Claims16
A method performed by a terminal for performing a slice-based cell reselection in a wireless communication system, the method comprising:
- deriving at least one reselection priority for the slice-based cell reselection based on information on a network slice access stratum group (NSAG) obtained from a non access stratum (NAS);
- in case that a cell in a frequency fulfils cell reselection criteria and does not support the NSAG, identifying whether the cell supports at least one NSAG other than the NSAG;
- and
- in case that the cell does not support any NSAG other than the NSAG, rederiving a reselection priority for the frequency as if none of at least one NSAG provided by the NAS is supported.
A terminal for performing a slice-based cell reselection in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- a controller coupled with the transceiver and configured to:
- derive at least one reselection priority for the slice-based cell reselection based on information on a network slice access stratum group (NSAG) obtained from a non access stratum (NAS),
- in case that a cell in a frequency fulfils cell reselection criteria and does not support the NSAG, identify whether the cell supports at least one NSAG other than the NSAG, and
- in case that the cell does not support any NSAG other than the NSAG, rederive a reselection priority for the frequency as if none of at least one NSAG provided by the NAS is supported.
